摘要
随着科技的进步,汽车工业同事也得到了迅速的发展,汽车已经走进寻常百姓家中。汽车渗漏问题,对于国产车来说,目前仍是比较普遍存在的现象。汽车的渗漏故障往往会严重制约汽车技术性能的发挥,导致润滑油、燃油的浪费,消耗动力,影响车容整洁,造成环境污染。由于漏油、机器内部润滑油减少,导致机件润滑不良、冷却不足,会引起机件早期损坏,甚至留下事故隐患。汽车漏电故障会导致车辆蓄电池亏电,出现起动困难或电器工作不良的现象,在有漏油现象的车辆上还有引发自燃的隐患。随着我国汽车生产和进口量得逐年增多,渗漏问题已成为汽车维修诊断领域中急需解决的一大难题。

Abstract
With the progress of science and technology, the automobile industry colleagues also obtained the rapid development, has entered the homes of ordinary of motor vehicles, for homebred car, is still mon phenomenon..Motor leakage tends to severely restrict the automotive technology and performance of the play, resulting in the waste of fuel oil, lubricating oil, power consumption, affect the vehicle clean, resulting in environmental to the oil spill, the interior of the machine lubricating oil is reduced, leading to poor lubrication, cooling machine is insufficient, can cause mechanical damage in early stage, or even leave hidden dangers of electrical leakage fault will cause the vehicle to battery power, appeared starting difficulty or electrical work undesirable phenomenon, the leakage of vehicle and cause bustion China's automobile production and imports have increased year by year, the leakage problem has e the automotive repair diagnostic field need to solve a big problem.
Key words: leakage fault,restricted,automotive technology and performance

第1章现代汽车渗漏故障
在进行汽车渗漏故障诊断前,首先要明白什么是汽车渗漏故障?汽车渗漏故障包括以下两层含义。
1、汽车部件或总成部分完全丧失原车设计所规定的工作能力的现象。
2、汽车的技术状
